I just opened a PR for reindex update by query tasks list and task cancel api support in #2017

we will release this under NEST 2,2 either friday or beginning next week.

Tomorrow i'm tackling the Graph API, depending on how fast that goes it'll make it into NEST 2.2 or we will have to do a separate NEST 2.3 release at the end of next week
